Bad odor refers to all gas substances that stimulate human olfactory organs, cause unpleasantness and damage the living environment. So far, there are more than 4,000 kinds of malodorous substances that can be felt by human sense of smell, of which there are dozens that are more harmful to human health. Some emit the smell of rotten fish, such as amines; some pungent, such as ammonia and aldehydes; some emit rotten eggs, such as hydrogen sulfide; some similar to rotten onions or rotten cabbage smell and so on. Stinky substances make people breathe poorly, nausea and vomiting, irritability, dizziness, and even smoked people, and when the concentration is high, it can make people suffocate and die.

In recent years, due to the odor emissions caused by the residents and enterprises more and more conflicts, residents petition more and more frequently. Environmental remediation, especially odor remediation has become an important project involving social stability and harmony. The time-sensitive and uncertain nature of odor emissions has made it difficult for environmental protection departments to collect evidence and enforce the law, so there is an urgent need to establish a real-time, efficient and fast automatic odor monitoring system to continuously monitor the odor situation 24 hours a day.

Test Items
